40 MHz MEMS XO with standby power-down
The 3.3V supply rail and ±50 ppm frequency stability suit it for general-purpose clocking in industrial-temperature environments (-40°C to 85°C). This makes the part viable for battery-powered or intermittently-sleeping systems where the clock tree can be gated off between active periods.
Housed in a 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.126" x 0.098" footprint matches standard 3.2x2.5 mm oscillator land patterns; no via-in-pad required. Surface-mount reflow profile per JEDEC MSL level applies — confirm bake requirements if the surplus stock has exceeded floor life.
